TEQ definition

TEQ means toxicity equivalence, the international method of relating the toxicity of various dioxin/furan congeners to the toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin.
TEQ. ’ means Toxic Equivalent, being the sum total of the concentrations of each of the dioxin and furan compounds specified in the first column of the table below multiplied by their corresponding TEF specified in the second column thereof:
TEQ means toxicity equivalence, the international method described in 40 CFR 266, Appendix IX, section 4.0, of relating the toxicity of various dioxin/furan congeners to the toxicity of 2,3,7,8-tetrachlorodibenzo-p dioxin.

Examples of TEQ in a sentence

  • COT recognised the lack of quantified TEFs for these compounds but said that “even if the TEFs for PXDDs, PXDFs and dioxin-like PXBs were up to four fold higher than assumed, their contribution to the total TEQ in the diet would still be small.

  • For dioxin contaminants the fertilizer must contain no more than eight (8) parts per trillion of dioxin, measured as toxic equivalent (TEQ).

  • The Discharger shall use the appropriate Toxicity Equivalence Factor (TEF) to determine Toxic Equivalence (TEQ).

  • For dioxin contaminants the fer- tilizer must contain no more than eight (8) parts per trillion of dioxin, measured as toxic equivalent (TEQ).

  • Where TEQ equals the product between each of the 17 individual congeners’ (i) concentration analytical result (Ci) and their corresponding Toxicity Equivalence Factor (TEFi)., (i.e., TEQi = Ci x TEFi).
